Specification of Letters Patent.

Application filed October 18, 1913. Serial No. 796,017.

To all whom it may concern Be it known that I, NILs FREDERICK AM-BURsnN, a citizen of the United States, and a resident of Brookline, inthe county of Norfolk and State of Massachusetts, have invented a newand useful Improvement in Clothes-Pounders, of which the following is aspecification.

My invention relates to clothes pounders and its object is to improvethe construction thereof in the manner hereinafter set forth.

One embodiment of my invention is illustrated in the drawings whichaccompany and form a part of this specification; but it will beunderstood that various modifications may be made in the particulardevice shown, without departing` from the spirit of my invention.

In the d awings, Figure 1 is a vertical section of a clothes pounderembodying my invention. Fig. 2 is an inverted plan view. Fig. 3 is asectional view on an enlarged scale showing a detail of construction.

In the particular drawings selected for more fully disclosing myinvention, l represents a conical body of any suitable material havingits lower edge turned inwardly and preferably, as shown in the presentinstance, this is accomplished by providing` the lower edge with a beadl. A second conical body 3 having its u pper edge turned outwardly, asfor example by beading it as shown at 3', is detachably secured to thebody l by forcing it up into the latter against the downturned edge 5 ofthe elastic diaphragm e, preferably of pure rub ber, so that saiddownturned edge, which preferably is thicker than the diaphragm itself,is compressed between the beaded edges of 'the conical bodies l and 3,respectively. In this way an absolutely watertight joint is formedbetween the diaphragm and the conical bodies and at the same time thebody 3 may conveniently be separated from the body l, either for thepurpose of renewing the diaphragm or inserting into the body l a largerconical body as indicated by dotted lines in Fig. l.

The upper portion of the conical body l terminates in a tube Q, to whichmay be secured by soldering or otherwise, a sleeve (3, the upper end ofwhich is provided with a flange 7 A hollow handle 8, the lower portionof which is provided with perforations 9, is disposed within said sleeveand the lower end thereof is secured to the diaphragm by means of thescrew l2 which passes through the washer l1 and the diaphragm, and isthreaded into the plug l() attached to the lower end of the handle. Itwill be understood of course that any suitable means may be employed forattaching the handle to the diaphragm so as to make a water-tight jointbetween them. A spiral spring ll, interposed between the flange 7 andthe collar 13, which is fixed to the handle, maintains the diaphragmflexed npwardly in the position shown in Fig. l.

On the downstroke of the clothes pounder, an.' and water will be forcedthrough the clothes and at the end of the downstroke or shortly before,the further movement of the handle with respect to the conical body7 lagainst the tension of the spring lll will llex the diaphragmdownwardly, thereby forcing an additional amount of air and waterthrough the clothes. On the upstroke the suction created will beincreased by the reaction of the diaphragm and spring, the air in, thebody l above the diaphragm escaping through the hollow handle by way ofthe perforations 9, so that there will be no interference with the freeaction of the diaphragm on account of compression of the air above thesame.

I claim:

l. A clothes-pounder comprising a conical body having a-beaded loweredge, a second conical body having a beaded upper edge, an elasticdiaplnfagm extending across the Iirst mentioned coni -al body andihavingits outer edge compressed between the beaded edges of said conicalbodies, and a hollow handle secured to said diaphragm.

2. A clothes-[wunder comprising a conical body having a beaded loweredge, a second conical body having a beaded upper edge, an elasticdiaphragm extending across the lirst mentioned conical body and havingits outer edge compressed between the beaded edges of said conicalbodies, and a hollow handle secured to said diaphragm and resilientmeans for maintaining said diaphragm llexed upwardly. Y

3. A clothes-pomulcr comprising two conical bodies, and an elasticdiaphragm, the outer edge oit' which is compressed between said conicalbodies.

4l. A clothes-pounder con'iprising two conical bodies and an elasticdiaphragm extending across the same.

5. A clothes-pounder comprising two Conioal bodies and an elasticdiaphragm extending across the same, said diaphragm having athiokenedouter edge and said outer edge E being Compressed between said conicalbodies.

In testimony whereof, I have hereunto subscribed my name this 17th dayof October, 1913.
